Цель изобретения - повышение нагрузочной способности распределителя момента. jThe purpose of the invention is to increase the load capacity of the torque distributor. j

Эта цель достигается тем, что распределитель момента снабжен конической передачей, включающей связанное с входным валом ведущее колесо и взаимодействующие с ним два ведо- jq мых колеса противоположного вращения, связанные каждое с одной из солнеч- , ных шестерён, два других одноименных основных звена соединены между собой а каждое из двух одноименных основных звеньев третьей пары соединено с одним из выходных валов.This goal is achieved by the fact that the torque distributor is equipped with a bevel gear, including a drive wheel connected to the input shaft and two driving wheels of opposite rotation interacting with it, each connected to one of the sun gears, two other main links of the same name are connected between each and two of the same main links of the third pair are connected to one of the output shafts.

На чертеже изображена схема распределителя момента.The drawing shows a diagram of a torque distributor.

Планетарный распределитель момен- ₂θ та содержит входной вал 1, два коаксиальных выходных вала 2 и 3, первый дифференциал, включающий солнечную шестерню 4, водило 5 с сателлитами и эпицикл 6, второй дифференциал, _2Jвключающий солнечную шестерню 7, во-: дило 8 с сателлитами и эпицикл 9 коническую передачу, включающую связанное с входным валом I ведущее колесо 10, взаимодействующие с ним два ведомых колеса 11 и 12 противоположного вращения , связанные посредством торсионов соответственно с солнечными шестернями 4 и 7, эпициклы 6 и 9 соединены Между собой, а водила 5 и 8 соединены соответственно с 35 выходными валами 2 и 3.The planetary torque distributor ₂ θ that contains the input shaft 1, two coaxial output shafts 2 and 3, the first differential, including the sun gear 4, carrier 5 with satellites and an epicyclic 6, the second differential, _2J including the sun gear 7, driven: 8 with gears and an epicycle 9, a bevel gear including a driving wheel 10 connected to the input shaft I, two counter-rotating driven wheels 11 and 12 interacting with it, connected by torsion bars with sun gears 4 and 7, respectively, epicycles 6 and 9 are interconnected, and carrier 5 and 8 are connected respectively to 35 output shafts 2 and 3.

Возможен также вариант выполнения распределителя момента, в котором водила соединены между собой, а эпициклы соединены каждый с одним из выход- ⁴⁰ных валов.An embodiment of a torque distributor is also possible in which the carriers are interconnected, and the epicycles are each connected to one of the output ⁴⁰ shafts.

Планетарный распределитель момента работает следующим образом.The planetary moment distributor operates as follows.

При вращении входного вала 1 мощность от ведущего колеса 10 двумя 45 равными параллельными потоками через ведомые колеса 11 й 12 противоположного вращения, связанные с ними солнечные шестерни 4 и 7, и. далее через водила. 5 и 8 передается на коаксиальные выходные валы 2 и 3 также противоположного вращения. Соединенные между собой эпициклы 6 и 9 под действием внутренних, равных по величине и противоположных по направлению реактивных моментов, неподвижны и служат опорным элементом при передаче мощности на выходные валы.When the input shaft 1 rotates, the power from the drive wheel 10 is two 45 equal parallel flows through the driven wheels 11 th 12 of the opposite rotation, the sun gears 4 and 7 associated with them, and. further through the carrier. 5 and 8 are transmitted to the coaxial output shafts 2 and 3 of the opposite rotation as well. The interconnected epicycles 6 and 9, under the action of internal, equal in magnitude and opposite in the direction of reactive moments, are motionless and serve as a supporting element when transmitting power to the output shafts.

Такое выполнение распределителя момента обеспечивает передачу через каждый из дифференциалов одинаковых по величине потоков мощности, равных половине подводимой ко входному валу мощности, что позволяет идентифицировать основные звенья дифференциалов и повысить их нагрузочную способность .This embodiment of the torque distributor ensures the transmission through each of the differentials of equal power fluxes equal to half the power supplied to the input shaft, which makes it possible to identify the main links of the differentials and increase their load capacity.

Claims

The invention relates to machine hatching and can be used as a planetary moment distributor, for example, in shipbuilding to drive screws of opposite rotation. A planetary gear, a housing, an input shaft, two coaxial output shafts and two planetary stages, including each sun gear, drove with satellites and an epicyclic, in which the sun gears are connected to each other and to the input shaft and epicycles are also connected to each other and to one of the known output shaft, first-stage carrier for IopMoaceiHo, and second-stage carrier connected to another output shaft. The disadvantages of this gear are the design complexity associated with the hull and the uniformity of power flows along the planetary stages. The closest to the technical essence of the invention is a planar torque distributor, containing an input shaft, two craxial output shaft and two coaxial differentials, each of which includes three main links, a sun gear, drove with satellites and C2J epicycle. In this device, the epicycles are interconnected, the sun gear of the first differential is connected to the input shaft, the carrier of the same differential is connected to the sun gear of the second differential and one of the output shafts, and the carrier of the second differential is connected to another output shaft. The disadvantage of this planetary moment distributor is that power fluxes of various sizes pass through the differentials, as a result of which, if the differentials are executed, one of them will be overloaded. The purpose of the invention is to increase the load capacity of the moment distributor. This goal is achieved by the fact that the moment distributor is equipped with a bevel gear, including a drive wheel connected to the input shaft and two driving wheels of opposite rotation associated with it, each with one of the sun gears, the other two the links are interconnected and each of the two identical parts of the third pair of the same name is connected to one of the output shafts. The drawing shows a diagram of the moment distributor. The planetary moment distributor contains the input shaft 1, two coaxial output shafts 2 and 3, the first differential including the sun six, drove 5 with satellites and epicyclic 6, the second differential including the sun gear 7, drove 8 with satellites and epicycle bevel gear an associated drive wheel 10 connected to the input shaft 1, two driving wheels 11 and 12 of opposite rotation interacting with it, connected by torsions respectively to sun gears 4 and 7, epicycle 6 and 9 are connected to each other, and Dila 5. and 8 are connected respectively with output shafts 2 and 3. It is also possible to implement a moment distributor in which the wiring is interconnected, and the epicycles are each connected to one of the output shafts. The planetary moment distributor works as follows. When the input shaft 1 rotates, the power from the driving wheel 10 is two equal parallel flows through the driven wheels 11 and 12 of opposite rotation, associated with it are the sun gears 4 and 7, and. then 0 and 8 are transmitted to coaxialvodil. The 5 output shafts 2 and 3 are also in opposite rotation. The connected epicycles 6 and 9 under the action of internal, equal in size and opposite in the direction of the reactive moments, are fixed and serve as a supporting element in the transfer of power to the output shafts. This embodiment of the moment distributor provides for transmission through each of the differentials of the same power fluxes equal to half of the power supplied to the input shaft, which makes it possible to identify the main links of the differentials and increase their load capacity.
